Janine Lahr is making her way back into the dance world after a fun & exciting 30 year career in the health and wellness industry. 


Although she has extensive experience in fitness, her love of movement actually started at the age of 4 when her parents enrolled her in the Eleanor Durkin School of Dance on Long Island, where she was raised. There she discovered a passion for music and would often find herself jumping at every chance she could get at leading & choreographing for school competitions.  


Janine’s adventurous side made her eager to travel in her 20’s and while working on a cruise ship in Alaska, she discovered yoga and began her journey to connect dance, fitness, and mindfulness into her work. The influence of all three is evident in her approach when designing & teaching her method. And her joy of movement is contagious.


Now residing in Doylestown with her husband and two young girls, she is excited to be a part of the Coalesce faculty and looking forward to meeting you in the new season to come.
